Solar in Wollongong — common questions
Is solar worth it in Wollongong?
Wollongong receives around 2,470 sunshine hours per year. A 6.6 kW system yields approximately 13,042 kWh/year with a payback of about 3.7 years. The Illawarra escarpment to the west can cause late-afternoon shading on some properties.
Are there heritage restrictions on solar in Wollongong?
Wollongong has 519 heritage items. Heritage conservation areas in Wollongong CBD, Bulli, and Thirroul may require council approval for solar. Check your address if near a heritage-listed building or conservation precinct.
What network serves Wollongong?

Does the escarpment affect solar in Wollongong?
Properties on the western slopes of the Illawarra escarpment or in valleys may experience shading from terrain in the afternoon. The aerial imagery analysis estimates roof area but cannot model terrain shading -- an on-site assessment is recommended for escarpment-facing properties.
What solar system size suits Wollongong homes?
